  1. Between 380W - 600W consumed every 24 hours.
  2. Mine is a PUHZ-W85VHA2-BS As per comments above, in summer the heating registers energy input, but no output. On the basis of those figures it seems to be using between 16W and 25W (380-600W per 24 hours), although how much of that is for the controller and how much for the heater I do not know.
  3. I've been following this for a while as I have an 8.5 kW Ecodan, package cylinder and FTC5 controller. I've been over and over my energy use and meter readings and certainly cannot find any evidence to substantiate the circa 250W standby, at any time of year. Having just checked, my unit is a VHA model.
  4. @ChrisOli The 1 metre is for visibility for road users and pedestrians, i.e. road safety - think car emerging from driveway. Without seeing exactly what the situation is at your location we are really just guessing as ultimately, it will probably be a matter of fact or degree. I would suggest the fact you have a letter means there is no or little leeway given your location. You can do nothing and wait for them to take enforcement action - serve a notice requiring removal. You can appeal such a notice, albeit no guarantee your appeal would be upheld. If you failed to comply with any notice you would be guilty of an offence, and probably be offered the opportunity to pay a fixed penalty (£1500 if memory serves). The local authority would also be able to take direct action to remove the fence etc and you would be invoiced for the cost (and doubtless pursued in court for non payment if you didn't settle the invoice). I would always advise engaging with the enforcement officer to see if there is any leeway / clarify what you could do in your location.
  5. A further update to this, replaced the bearings with SKF as recommended. So far so good - a real difference, whisper quiet.
  6. @rh2205 Do you know the breakdown between DHW input energy and Heating? 50/50 ? Your figures seem quite remarkable, and from a bill paying point of view most welcome. I'm up in Orkney, and very similar to @ProDave in terms of input energy for heating, albeit we do not have a wood burner / secondary heating source. Not as cold here but as you would imagine, very windy, which in effect, drives as much heat loss as colder temperature does. Looking back at my energy usage, year to year there can be up to a 15% variation in the amount of heat energy required, with the total figure ranging between the calculated energy demand for average outdoor air temp and minimum outdoor air temp. We heat the house to 21.5C, with the ASHP coming on as required to maintain that temp. Within the house the impact of household gains are evident as occupation moves between different parts of the house +/-0.5C. The ventilation rates set in specific rooms also impact on the room temp by perhaps +/-0.5C We meet some passive house criteria, but certainly not all, and our house design, for want of a better description, two interlinked bungalows, means we have a lot more exterior wall standing up to the elements. We have 155m2 internal footprint with one upstairs attic room. We have additional areas of vaulted ceiling as well meaning our house volume is around 473m3, so roughly speaking the equivalent of a 200m2 standard sized room building.
  7. Quick update with what I hope is a useful tip. In the end I went for simple mechanical removal with a Stanley blade scraper. To reduce friction and prevent the blade digging into the shower tray, I used a little lightly diluted washing up liquid to wipe over the silicone and the blade. This worked brilliantly and let the blade glide on the shower tray and easily break the bond of the silicone for removal. First time I've tried it but worked a treat. Likewise having cleaned off the old silicone I used wet wipes to remove any final residue (when you see what they do to your hands I can't fathom why you would want to use them on a baby!), I did a final clean / degrease with meths before applying the new silicone, finished as suggested with profile tool.
  8. Short update to this. The replacement bearings seem to have failed, as the fan has been getting noisier and noiser. This may simply be the fact the bearings were cheap and poor quality, but nonetheless annoying. I have therefore replaced them again but there doesn't seem to be much in the way of improvement (same batch of bearings). I really don't want to have to replace the fans themselves given the cost, but other than getting some different bearings there's not much I can do or think of doing. Given the cost of replacement fans, and the fact the other fan is now making a little noise, if new (better quality?) bearings don't work, I'd be as well replacing the whole unit given the cost of the controller/control board (also known to fail) runs to several hundreds as well. While nothing lasts forever, and I accept that bearings costing less than £1 fall into that category, its still frustrating. Having looked online, there are several suppliers from which I can buy the right size bearing. Can anyone suggest a quality bearing brand to go for (rather than the no name ones I've tried)?
  9. One point to bear in mind, whenever a government spokesperson hails the amount of renewable heat energy being generated, he or she is referring to the notional total as derived from the kWh calculated through RHI and other like schemes. All good you see - takes us closer to net zero, so a win all round.
  10. Don't know what you have planned for the oak, but do not burn it. They can be sold for surprisingly big money. Can put you in touch with a furniture maker here who would be very interested, including some of the smaller limbs.
  11. 5 years on and no issues for us.
  12. They have performed as PVGIS suggested, lower output compared to mounting on the roof, but reasonable none the less. The array I have produces circa 20% less compared to being roof mounted at 45 degree pitch. Mine are fixed to the garage wall so no issues with wind (which can get quite brisk here!)
  13. I believe suppliers are also permitted to apportion the cap between standing charge and unit price as they see fit, so there will be some minor variation there as well.
  14. Not sure as it's not something I've looked into (not being especially keen on the idea). Got a couple of folk I can ask and will update if anyone of note to add.
